Marston or MAKING Application filed August 15,1921.

'f and State of Illinois, have invented a certain new and useful Improvement liIethods of Making Packages, of which the following is a full, clear, concise,rand exact description, reference being had Vto the accompanying drawings, forming a part of this specication. y

Vluy invention relates to containers and the method of making the same, and is concerned particularly with containers for cemcntitious material such as plastic flre brick.

Containers entirely of wood, by reason of their liabilityto breakage in the course of transportation are not adapted for materials of the weight and nature of plastic ibrick. Moreover, when such-wooden containers are employed, I find that the material dries out and does not reach the consumer in proper condition. While a container entirely of sheet metal willA keep the material'in excellent condition, such containers have been impractical and have not come into use fork the purpose indicated because of their in-' ability to hold against bulging andiother distortion .whenv lled, without expensive construction and reinforcements, and, since Y the Containers are used once and discarded, such expense is prohibitive1 A container for the purposes for which the containerof my invention is provided must be provided at a comparatively low cost. A container too ex pensive to be discarded after one shipment makes collecting and reshipping of the empty container necessary, the cost of which renders the use of the container prohibitive.

The object of my invention is the provision of a novel, simple andinexpensive container which will keep the material in excellent condition from the time it leaves the factory until it reaches the consumer,

. and which will not bulge or become otherwise distorted, but will hold up when lled. In addition to the aforesaid functional advantages and structural superiorities, I aim to provide a container which may cheaply made up and packed that after bengkused once, it may be disoardedwithout appreciable loss. l 1. r Y

I accomplish the objects of my invention by the provision of a Container comprising be so' PATENT oFFlcI-z.

a cylindrical sheet metal shell having woodenend members held together by nails anchored in the contents to form a complete package. rlie sheet metal shell keeps the material inA excellent condition, while the Wooden end members provide the necessary .stiffness so that the shellwillhold against bulging and such other distortion as has rendered containers entirelyof sheet metal impractical for the purpose indicated. The relative-dimensions of the sheet metal shell and the wooden end members` are such that the condition maintaining qualities vof Ithe shell are not impaired. The originally loose material, of course,stends to cake, and at the` ends, where Ait is in lcontact with the wood, forms quite a hard 'crust and it is in this crust that the'nails are anchored. f y l In addition to the advantages alreadyy set out, construction of the containerl is facilitated by reason of the Icombination of the sheet metal shell with the wooden end members and certain advantageous Mdetails `of construction are made possible.`

My invention contemplates a novel method whereby this desirable package is produced, and this method is made the subject matter of the appended claim.

In the accompanying drawings: Figure 1 is a Yperspective view. showing the p iece of sheet metal employed-Hin making upa container in accordance Vwith my practice ofl my invention and the stepV of forming the same into the shell portion thereof; V Y, y

VFigure 2 is a fragmentary perspective view showing one of the wooden end members inserted into the shell.;

rFigure 3 shows the step of securingthe wooden end member in place;

Figure 4 shows the stepl of arranging the opposite end in place;

Figure 5 is a fragmentary perspective view of the completed. container; and

Figure 6 is a fragmentary vertical sectional view taken substantially onthe line 6 6 of Figure 5.

yA piece of suitable sheet metal l of such dimensions that it may be rolled 'or otherwise -formed into the uniform cylindrical shell 2 is the basis of the formation Vof the container. The adjacent longitudinal edges of the shell 2 are joinedalong the Seam 3 as ,by bending @I lapping @han bassist@ cooperative engagement as shown at 4 or in anj'o'ther suitable manner.

A suitable wooden end member or bottom 5 is then arranged in one end of the shell 2,-being spaced in from the end of the shell substantially as shown. That portion of the shell projecting outwardly beyond the end member 5 is provided with a plurality of slashes or cuts 6 extending outwardly from the end member 5 to the adjacent end of the shell 2. These slashes or cuts provide a plurality of flap or tab portions 7 which flap portions 7 are bent in along the outer face of the end member 5 and nailed or otherwise suitably secured thereto.

The cuts or slashes 6 are preferably at an ang'jle as shown in Figure so that when bent in along the outer face of the end member 5 one corner of `each of the flap portions 7 `will overlap the adjacent corner of the adjacent flap portion. Then the overlapping corners aresecured to the endmember, as bymeans of thenails 9, ythe adjacent corners of the adjacent flaps are securely held thereby. rlfhe nails 9, 9, are preferably of such length as to extend through and beyond the end 5.

A groove or bead S in the shell 2 extending circumferentially around thel edge of the endv member 5 serves the dual purpose of reinforcing the end of the container and holding or retaining the end 5 in place untilvfinal attachment to the shell 2 is effected. This bead also serves as a limiting circle for determiningthe line on which to fold vthe flap portions 7 and limits the folding line of all flap portions to a common height for producing a smooth planar end on the container. The bead 8 may be omitted and the end 5 otherwise held in place as by vmeans of a form or by inverting the container upon a post or the like until final attachment is effected. Similar circumferential grooves or beads 10 may be provided to strengthen the shell within its length.

The cuts or slashes 6 may be provided in the lsheet metal at any desired stage in the formation of the container. They may be provided for example, before rolling or forming the sheet metal into the shell 2, or even after insertion of the end piece 5. The grooves or beads may likewise be provided in the sheet metal at any desired stage in the formation of the container, but the end grooves or beads 8 are preferably formed before the flap portions 7 are bent. The end 5 being secured in place, the container is ready for the reception of the plastic fire brick or other material to be packedl therein. In the case of plastic fire brick, for example, the loose mate-rial is packed into the container up to the level at which it is desired to position the end member or cover 11. The end member 11 is then laid firmly upon the contents in the:

open end of the shell 2, which end lite the opposite end of the shell is provided with a plurality of slashes or cuts 12. The inward crimp of the adjacent end bead 8 preterably assists in positioning this end member at right angles to the length. of the shell and firmly holds the end member in place. lf desired this bead or crimp in the shell can be formed after the insertion of the end member to partly compress crimp into the wood. The flap or tab portions 13 provided by the slashes or cuts 1Q are bent in along the outer fawce of the end member 11 and along the limiting circle formed by the bead S and are nailed as shown at la or otherwise suitably secured thereto. Nails are preferably employed and the shanks thereof preferably extend through the end member and into the plastic material 20, as shown in Figure 6, to form an anchoring connection between the container and the material which will not interfere with the Convenient removal of the material from the container. The end (Figure 6) of the contents 20 packed in the container becomes hardened to protect the material inside.V it and provides admirable anchoring means for the nails 14. The material is removed by simply chopping the container open.

As illustrative of the relative dimensions of a commercially practicable container which l at present construct employ No. 24; gauge sheet metal for the shell. For this thickness of metal l employ wooden end members of inch thickness. The container is substantially 18ginches across and 34 inches in length. lt will be noted that with this relatively light gauge of sheet metal it the is imperative that a relatively thick, rigid end member be employed to preserve the cylindrical form and prevent bulging at the ends.. This the wooden end members provide at scarcely appreciable cost and with the added advantage of affording a convenient and inexpensive manner of securing the sheet Ymeta-l shell to the end heads.

l claim:

The method of making a package comprising filling an open top closed bottom container' with loose material to a level near the topv thereof, supporting a cover on said material within the margin of said container above said level, bending the top peripheral margin of said container inwardly over said cover, and driving fastening means through said margin into said cover, utilizing said material to support said cover while said fastening means are being so driven in.

In witness whereof, l hereunto subscribe my name this 6 day of August, 1921.
